It is the existence of the metamorphic core complex that causes the different degree evolution of the hydrocarbon source rock in different areas and also controls the lateral changes of the hydrocarbon phases.

通过对库车坳陷变质核杂岩分布、烃源岩演化程度和地温梯度变化的分析认为：库车坳陷变质核杂岩的分布可能极大地影响了不同区带的地温梯度，从而影响了不同区带烃源岩的演化程度并控制了油气相态的横向变化。
